My Dear Sleeblurk,
I must congratulate you on a sure-to-be-successful patient. Once at the party, your patient, non-chaliced as he was by his sheltered childhood, sampled every form of temptation he found there, and rather enjoyed them all. What's better, when asked where he was by his mother, he told a lie! Not only does this ensure his acceptance into the damned crowd and to future parties, it also means the beginning of a possible bad relationship with his parents!
You've done well, Sleeblurk, but your job isn't over yet. Your patient is still technically an agent of the Enemy; you have to make sure that he severs this relationship. You must also ensure that, once the patient's relationship with the Enemy is severed, it stays that way. Your job is only over when the patient dies. Which reminds me: if you can, get your patient to take his own life once he's fully corrupted. Not only is this a sign of great talent, it also makes for a delightful taste when the ceremony of his entry into Our Father's House takes place. Continue your streak of success and you will be sure to be promoted to seniority nearly as low as mine,
Your Affectionate Great-Uncle,
Screwtape
